 Trustindex verifies that the original source of the review is Google. I have been going to RCB for about 5 years. The staff is great! Raj the owner is very easy to deal with and is very fair. I recently wanted to sell some jewelry, I didn’t feel comfortable going to other places so I went back to Raj. He is a gentleman and treated me with respect.i sold my jewelry to him with no regrets. If I come across some jewelry at home I want to sell I will go right back to RCB. I also told people I know how great the place is and they’re going to go as well. I wish I could give 10 stars, but 5 is the max. Thank you Sean R.

 Trustindex verifies that the original source of the review is Google. We have sold items here on a few occasions and each time the experience was terrific. Always polite and always explained every step and results of every test. A great place with good honest people. I would highly recommend them.

 Trustindex verifies that the original source of the review is Google. They are most respectable people that I have ever met. He explained everything on how it works and what it is worth. He also stated no one would beat the price that he offered me. So being the first place I went to, I had to check out two other places . Well he was absolutely correct. They didn’t come close to what he offered. Not even close. So of course I went back and completed selling the gold . I was so pleased to see how honest he was. I will definitely be back.
